Abstract
Apparatus and methods for variable capacitor arrays are provided herein. In certain configurations, an apparatus includes a variable capacitor array and a bias voltage generation circuit. The variable capacitor array includes a plurality of metal oxide semiconductor (MOS) variable capacitor cells, which include one or more pairs of MOS capacitors implemented in anti-parallel and/or anti-series configurations. In certain implementations, the MOS variable capacitor cells are electrically connected in parallel with one another between a radio frequency (RF) input and an RF output of the variable capacitor array. The bias voltage generation circuit generates bias voltages for biasing the MOS capacitors of the MOS variable capacitor cells.
